SPECIFICATION forming part of Letters Patent N o. 710,207, dated September 30, 1902.

Application iled May 15, 1902. Serial No. 107,379. (No model.)

To all whom, it may concern:

Be it known that I, EMIL PHILLIPsoN, a citizen of the United States, residing in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Stoppers for Tater-Bottles, of which the following is a specification.

This invention relates to an improved stop? per for water-bottles of that class which are made of soft rubber and used either with hot or cold water for various applications to the body, the stopper being designed with the view of being opened, so as to permit the filling or discharging of the bottle, but without entirely removing the stopper, so as to prevent its getting lost or mislaid; and for this purpose the invention consists of a stopper for water-bottles which comprises a stopper having a threaded shank engaging a correspondingly-threaded socket of the reinforcing bushing of the neck of the bottle, so as to permit the opening of the stopper without detaching the saine.'

The invention consists, further, of a stopper for water-bottles which is provided with a threaded shank engaging a correspondinglythreaded socket of the reinforcing-bushing of the neck of the bottle and a stop device between the shank and socket, so as to prevent the detaching of the stopper after opening it to some extent out of the neck of the bottle.

In the accompanying drawings, Figures l, 2, 3, and 4L are vertical central sections of different forms of my improved stopper for water-bottles, showing different modifications of the same, the stopper beingshown in closed positions.

Similar letters of reference indicate corresponding parts.

Referring to the d rawings, A represents the neck of a soft-rubber water-bottle of the usual construction.

B is lthe funnel that extends around the stopper, said rubberfunnel being made in one integral structure with the neck of the bottle. The neck A is reinforced by a cylindrical bushing O, which is made of brass or other metal and provided with an exterior rim a at its upper end which forms a seat forthe rubber packing-ringorgasketd,which is retained in any suitable manner at the undersideoftheheadofthestopperD. Thestopperis provided with athumb-piece D for being readily taken hold of in opening or closing the same. The stopper D is provided with a shank E, the simplest form of which, as shown in Fig. l, is provided with an exterior screwthread e at its lower end that engages an interiorly-threaded socket e', supported on the perforated bottom c of the bushing O, said threaded portionV of the'shank being of sufcientlength so that the stopper can be lifted for a certain distance above the rim of the bushing without detaching the threaded shank from the socket. In this manner the bottle may be filled or emptied without detaching the stopper. In some cases, however, it is desirable for the purpose of positively preventing the detaching of the stopper when opening the bottle, so that when the threaded shank becomes released from the threaded socket a positive means will arrest the motion of the stopper. For this purpose the constructions shownin Figs. 2, 3,and 4 may be used. In Fig. 2 the shank E is made .hollow and provided with an interior screw-thread e2. Above the threaded part is arranged an interiorshouldere3,which is provided with a threaduopposite to the thread in the shank. The hollow shank E engages a stationary eXteriorly-threaded spindle F, attached to the perforated bottom C- of the bushing, said spindle being provided with a stem f, extending into the hollow shank E' and provided at its upper end with a head'f, threaded oppositely to that of the larger portion of the spindle F, so that when the thread e2 runs oft` the spindle F the stopper will turn loosely, swivellike, on the stem f, the stopper being only detached when bringing the threaded shoulder e3 into engagement with the threaded head f' by turning the stopper in opposite direction. Without turning in opposite direction the stopper cannot be detached, as the threaded head j" of the stem f forms with the shoulder e3 a stop device for the stopper and prevents its detachment from the bushing of the water-bottle. Fig. 3 shows the same arrangement, only reversed. In this case the lower end of the shank E? is exteriorly threaded, the direction of the screw of the shank be- IOO 1 ing opposite to that of the head f2 of the stem f3 of the shank. The threaded portion of the shank E2 engages the socket F, supported by the bottom of the bushing, while the smaller end, threaded in opposite direction, engages a correspondiugly-threaded portionf4 in the end ofthe socket. In Fig. 4 the stop is made in connection with a stop-screw f, that abuts against the enlarged threaded end of the shankE3 and prevents thereby the detaching of the stopper until the stopscreW has been removed. In all the constructions shown in Figs. 2, 3, and 4, however, the stopper is arrested when the same is lifted to a certain extent sufficient to permit the free unobstructed filling and discharging of the bottle. Any other stop mechanism for arresting the stopper after the same is raised to a certain extent may be used, as I do not desire to confine myself to the special constructions shown.

It is obvious that the threads of the shank F and of the head f may be made in the same direction instead ofin opposite directions, as shown, as the disengagement Which occurs when the shank is screwed out of its socket, so that the same is free to turn Without being moved in either direction, is sufcient to prevent the inadvertent removal of the stopper by the user.

By the construction of the stopper described the bottle can be filled and discharged Without detaching the stopper, so that the same is always at hand and not liable to get lost or mislaid.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the neck of a water-bottle, of a bushing secured therein, said bushing having a suitable screw-threaded portion, a stopper having a thumb-piece, a gasket fitted on said stopper, and a screwthreaded lshank on said stopper adapted to engage said threaded portion of the bushing, substantially as set forth.

2. The combination, With the neck of a Water-bottle, of a bushing secured in the same, said bushing being provided with a perforated bottom having acentral screw-threaded portion, a stopper provided with a thumbpiece, a gasket fitted on the head of the same, and a shank provided With a threaded portion adapted to engage the threaded portion of the bushing, substantially as set forth.

3. The combination, with the neck of a Water-bottle, of a bushing secured therein, said bushing having a suitable screw-threaded portion, a stopper having a thumb-piece, a gasket fitted on said stopper, a screw-threaded shank on said stopper adapted to engage said threaded portion of the bushing, means for preventing the accidental detachment of the stopper from said bushing, and means for permitting the detachment of the same, substantially as set forth.

4. The combination, with the neck of a Water-bottle, ot a bushingsecured in said neck, an interiorly-threaded socket supported by said bushing, astopper provided with a shank having a threaded portion engaging said socket, and a stop device between the socket and shank for arresting the motion of the stopper, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
